Abstract

The invention belongs to the technical field of electric power, and particularly relates to a manufacturing method of multi-purpose zinc clad steel. The manufacturing method comprises the following steps that chemical-free environment-friendly treatment is performed on the surfaces of steel wires; surface cleaning treatment is performed on the steel wires by the aid of a belt sander; the cleaned steel wires are heated by an intermediate-frequency furnace, then the steel wires and two zinc rods enter a continuous cladding machine simultaneously for extruding, the zinc clad steel is obtained, the heating temperature of the intermediate-frequency furnace is controlled to range from 200 DEG C to 250 DEG C, an extruding mold and a guiding mold are assembled on the cladding machine according tothe product requirements, the nasal fossa sizes for mold assembly are controlled to range from 3 mm to 6 mm according to the diameters of the steel wires, the mold cavity temperatures are controlled to range from 150 DEG C to 250 DEG C, the rotating speed of an extruding wheel is controlled to range from 3 rpm to 7 rpm, and the extruding speed is controlled to range from 70 m / min to 120 m / min; andcomposite metal drawing is performed on zinc clad steel busbars after cladding. According to the method, the whole production process is free of chemical pollution, the method is different from all existing zinc clad steel technologies, and flexible production is realized.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a method for manufacturing multipurpose zinc-clad steel. Background technique [0002] At present, zinc-clad steel is widely used in the field of electric power, and the manufacturing methods are different according to the purpose of use. There are three main methods: 1. Use a container to heat the zinc block and coat it on the surface of the steel wire; 2. Use the heated zinc block to extrude it. Press on the surface of the steel wire; 3. Electroplate a layer of zinc on the surface of the steel wire by electroplating; the first method is mainly used for galvanized steel wire for overhead conductors. There is a gap between the steel wire and the zinc layer, which is very easy It falls off, which greatly reduces its anti-corrosion life. It is difficult to ensure the uniformity of the thickness of the galvanized layer, and the production of thick galvanized is ex...
